Ready For Gravel Grinding, Singletrack Shredding, & Everything In Between
Powerstrap X4 is a versatile gravel-focused shoe, created for a close fit, high performance, and comfort when your drop-bar adventures take you past the limits of traditional paved roads. The Powerstrap X4 is a member of Fi’zi:k’s Terra off-road series, designed to take you beyond your boundaries and ready for any terrain, any weather, and any style of riding. A simple, efficient, and reliable Powerstrap Velcro closure system gives your foot an enveloping and secure fit. With its two robust straps, the upper’s instep and midfoot are separately adjustable for customized fit and compression.
The close-fitting upper is paired with a whole new outsole engineered specifically for the gravel adventure rider. The X4 is a carefully considered balance of stiffness and comfort for an efficient ride on mixed surfaces, combining nylon with targeted stiffness and a rubber tread for effective grip and durability. Whatever adventure you choose, grinding gravel or gliding through flowy singletrack, there’s a shoe that does it all: Terra Powerstrap X4
